The 21SX1-T is a snap action, limit switch with a wide range of applications and working principles. The switch is designed to provide reliable, repeatable performance in a variety of applications, from industrial control to consumer products. It can be used to control a broad range of applications, from basic on/off switching to complex multiple stage operation control.

The 21SX1-T is a single pole, double throw (SPDT) switch with a snap action mechanism. This mechanism uses a plunger that is moved by a spring-loaded lever or rod. The force of the spring and the mass of the plunger are chosen to create a pressure that is just below the rated operating force of the switch. When this pressure is exceeded, the plunger snaps in the opposite direction, causing the contacts to change state – either opening or closing the connection.

The 21SX1-T has a variety of applications. In industrial and commercial settings, it can be used to control motors, conveyor systems and other automated systems requiring precise timing. In consumer products, it can be used to control lighting, audio systems and other consumer electronics. The switch can also be used in the medical field, where it can be used to control instruments, equipment and other devices.

The 21SX1-T is available in several contact configurations. These include normally open (NO), normally closed (NC) and changeover (CO) contacts. The switch is also available in a variety of mountings and actuator styles, ranging from push buttons to levers. The contacts are rated for up to five amps, depending on the model chosen.

The operation of the 21SX1-T is relatively simple. When the plunger is pushed in, the contacts in the switch remain closed. When the plunger is released, the contacts open. The plunger is held in the closed position by a spring or other mechanism. This ensures that the switch remains in the same position until it is actuated by an external force.

The 21SX1-T can also be used in safety circuits. The switch has a built-in safety feature, which prevents it from opening if the plunger fails. The contacts in the switch remain closed until they are manually reset. This ensures that the switch remains in a safe condition until reset and prevents unexpected power outages.

In summary, the 21SX1-T is a highly versatile snap action, limit switch that is suitable for a wide range of applications. It is available in several contact configurations and actuation styles and has a built-in safety feature for added protection. The switch is easy to install and operate, making it an attractive option for industrial, commercial and consumer applications.
